How to cool your telescope

bloodhound31 · June 26th, 2008, 07:00 AM

Well, I raided the tip for some computer fans and coolers....I have been a busy boy tonight.

I was a bit nervous about pulling the scope to bits to do this, but it is well and truly out of warranty now and I am fairly confident I know what I am doing....

I will be writing a FULL tutorial and have LOTS of photos, so stay tuned folks!

Whoaa...you have been busy. And that looks like some system for cooling. Is there a liquid going through the cooling blocks or are they simply moving the heat off the assembly by the contact with the metal surface? I'd be interested to hear what kind of cooling temperature you reach and how quickly after turning on the fans. Any fears of the fans causing vibrations when you're imaging?

I don't have peltiers underneath yet. I will give it a try without them to see the results. Later I might put peltiers under the heat sinks.

The fans get turned off during imaging.

All done!!!

With inspiration and guidance from Paul and Anthony (They developed this method) from Southern Celestial Pole, I have completed an active cooling modification and tutorial on my C11 SCT, using Peltier coolers.

My thanks to both of them for their encouragement and backing to share this around.

Cheers,
